The rules are simple: I want a picture that meets the following criteria. If multiple pictures are submitted, I will choose the best one. If no pictures meet my (fairly low) standards, no money will be awarded. Draw-er of the best accepted picture gets 10 BTC and the mysterious potential for more.

Criteria

Drawing should be black and white, either digitally composed or a high-quality scan. Using xkcd for reference on this point will give you the general idea.

Drawing should depict a large cat (Felis Catus) facing the viewer, and a small mouse dressed as a ninja also facing the viewer. Cat may optionally be eyeing the ninja mouse out of the corner of its eye, or licking its lips, but the basic look is to be police lineup style.

Drawing should be a simple line drawing with no background elements. Excessive detail is undesirable.

edit: Deadline for entries is 6am UTC.

That's it. Go!

Hey, non-original is perfectly fine with me--although attribution is nice so I do prefer it. This has been an incredible response! I love all your pictures: great efforts everyone!!

So far I like ChaosFox's drawing the best; purplezky's interpretation has the mouse looking like the sinister one; and shooter_mcgavin's cat is way too cuddly for what I need. Plus, vectors kick butt. But I'm very impressed with shooter_mcgavin's photography skills--it's hard to photograph line drawings!

One thing I forgot to do is give out a deadline. Hopefully this won't thwart anyone already working on a drawing, but shall we say 6 am UTC? I'm open to changing it if it's a problem.

Very nice, joeydangerous. I think I will have to extend the "mysterious potential" part to at least one runner up, no matter which one I pick!

@Garrett with entries flowing in this fast I think that might be too long. I don't want too many people to feel disappointed! What's her user nick though?
